Subject: Inorganic Chemistry · Chapter: Coordination Chemistry · Topic: Electron Transfer Redox · Exam: NET JUNE 2019 · Marks: 2 · Difficulty: Medium
For the given reaction \[ \left[{ }^{*} \mathrm{Co}(\mathrm{L})_{n}\right]^{2+}+\left[\mathrm{Co}(\mathrm{L})_{n}\right]^{3+} \rightarrow \left[{ }^{*} \mathrm{Co}(\mathrm{L})_{n}\right]^{3+}+\left[\mathrm{Co}(\mathrm{L})_{n}\right]^{2+} \]
the correct statement with respect to the rate of electron transfer process is o-phen = o-phenanthroline ; *Co is labeled atom (a)fast electron transfer; $\mathrm{L}=\mathrm{NH}_{3} ; \mathrm{n}=6$
(b)slow electron transfer ; $\mathrm{L}=\mathrm{o}$-phen; $\mathrm{n}=3$
(c)very slow electron transfer ; $\mathrm{L}=\mathrm{NH_3}$ ; $\mathrm{n}=3$
(d)very slow electron transfer: $\mathrm{L}=\mathrm{o}$-phen; $\mathrm{n}=3$
